Be it known that I, WILLIAM H, Scrroou- MAKER, a citizen-of the UnitedStates, and .a resident of Montclair, county of Essex, and

State of New, Jersey, have invented certain new and: useful Improvementsin Methods of Treating Roads, of which-the following is a full, clear,fand exact' description.

. My invention re'lates to amethod of treatio ing road's to lay thedust. a'ndproduce a smooth, hard and neat wearing surface'and'comprises'raising' the'adust from the road surface and applying a sprayof suitable liquid to the dust soraised and then'permitting theso-impregnated dust to fall upon the road bed;

In'the accompanying drawings I illustrate more or less diagrammaticallyapparatus for carrying out my invention. r

In said drawings: Figure 1- shows a $16.8

'2 an end-view thereof.

In carrying out my invention I pr as follows: Flrst, the finely dividelevation of-a suitable apparatus, and Fig.

termed dust lying on the road surface in suc condition that itmay beblown with the intimate mixture of the oil and dust. Preferably the oilspray is produced and propelled by anair blast 0r jet; Finally, theintimate mixture of dust particles and oil particles is precipitated tothe road bed or surface from which the dust was raised.

- This is best accomplished naturally, through the force of gravity. a I

The result isthat the surface oftheroad 'is covered with the dust, theparticles of ,which areeachl intimately-united with. the

jflmethodbfoiling'roa simply Ithrowfi -on -thefdust covered road andpartlysoaked into partoi the'dust, but is intimately united with' eachand'e'very particle and makesa-iiniform covering which.

\Vhile the aforegoing detailedmcthod of procedure is deemed preferable,I 'would" point out that if conditions are such as to warrant it, anatomized jet orspray of oil or other liquid may be thrown directly onthe road bed, combining with the dust particles either completely onthe'road bed or partly on the road bed and partly in the atmosphere.

In the accompanying drawings I have -apparatus suitable for carrying outmy 1n-' vention; i
